DISTILLING AND EilEATING APPARATUS.

Application filed January 2. 1919.

T 0 all whom it may concern.

Be it known that I, llosnnr S. Mnlxns, a citizen of the United States, residing at Arkansas t/ity, in the county of Cowley and State of Kansas, have invented a certain new and useful improvement in Distilling and Heating Apparatus, oi which the following is a specification.

lily invention relates to improvements in distilling and heating apparatus.

@ne of the objects of my invention is to provide a distilling and heating apparatus which is simple in construction, cheap to manufacture and efficient in operation.

My invention provides further a novel boiler and novel means for heating water therein.

My invention provides still further novel distilling means by which water may be distilled and drawn off or automatically discharged back into the boiler vhen it is not being drawn oil for use elsewhere.

The novel teati 3 ct my invention are hereinafter tally described and claimed.

In the accompanying drawings which illustrate the preterred embodiment of my invention,

Figure 1 is a view partly in side eleva tion and partly broken away and in vertical section 01 my improved apparatus.

2 is a view partly in end elevation, partly broken away and partly invertical section of the apparatus.

Fig. 8 is an enlarged vertical sectional view of one oil. the check valves which are located in the pipes which discharc'e into the headers.

Similar reference cha 'acters designate similar parts in the different views.

1 designates the body oi a horizontal boiler provided at its upper side with a vertical steam dome 2 and provided at opposite ends with heads 3, which are secured by bolts l to two peripheral annular flanges 5 secured respectively to the outside of the boiler adjacent to its ends.

Encircling the boiler l. and spaced apart therefrom to form a line space is a casing 6, which also is provided at its upper side with a smoke pipe 7, which encircles and is spaced apart from the steam dome 2. The casing 6 is provided below the boiler 1 with a vertical tubular extension 8 which forms a vertical passage communicating at its upper. end with the line space around the boiler.

Specification of Letters Patent.

Serial No. 269,255.

At opposite sides respectively of the extension 8 are two headers, each consisting of a hollow cast member 9 to the outer side of which is secured by bolts 10 a cover plate 11. The header members 9 are respectively connected with the lower side of the boiler l by pipes 12. Inclined tubes 13 have their opposite ends respectively secured to the members 9 and interiorly communicating with the twoheaders.

The tubes 13 and the boiler 1 may be heated in any desired manner as by means of a gas burner 1st located in the extension 8 below the tubes 13, or by means of a coal furnace 15, upon which the casing extension 8 rests.

Each header is provided with a vertical extension 16, in which is fitted and supported an arcuate plate J17 which is fitted to and supports the under side of the boiler 1.

Embracing the boiler l are two arcuate members 18, which are T-shaped in cross section and which are provided each with a laterally extending flange 19, which engages the inner side of the casing 6 and holds the latter in spaced relationship to the boiler l.

ll. conductor 20 has one end connected to the steam dome 2, the other end being connected to the left header member 9, as viewed in Fig. 'l, the conductor 20 is provided with a vertical condensing coil 21, located in a condensing tank 22, which has connected to its bottom an intake water pipe 23, provided with a shutoff valve 2%. The conductor 20 intermediate of the dome 2 and tank 22 is provided with a shut-oil valve The condensing coil 21 is arranged so that steam from the boiler dome 2 passes downwardly through and is condensed in the coil 21.

The conductor 20 intermediate of its discharge end and the tank 22 is provided with an outlet for distilled water, preferably comprising a branch pipe 26 which discharges downwardly into a distilled water container 27, near the bottom thereof. The container 27 is provided near its bottom with a draw-off cock 28. The upper end of the container 27 is provided with an air vent comprising a vertical tube 29, the upper end of which discharges to the atmosphere and the lower end of which communicates interiorly with the container 27. In the container 27 is a float valve 30 having an upwardly extending stem 31 which extends right hea through the tube 29 and serves as a guide for as to support the valve 30.

The conductor 20 intermediate of the branch 26 and the discharge end of the con-- ductor is provided with a check valve 33 oi" any ordinary construction, which opens toward the discharge end of the conductor 20.

Extending upwardly through the bottom of the tank 21 to near the top thereot is a conductor 34* which serves to carry off the overflow of hot water from the tank 22 and which is provided with two discharge branches 35 and 36 provided respectively with a shut-oil valve 37 and a check valve 38. The branch 36 is connected with the right header member 9, as viewed in Fig. 1, and discharges interiorly into the right header. The check valve 38 may be oi any ordinary construction, so long as it pens toward the header to whlch the branch 36 is connected.

in Fig. 3, is illustrated a check valve adapted to be employed in the branch 36. Referring to l ig. 3, 39 designates a vertically slidable valve adapted to rest by gravity upon a seat 40 in the casing of the check valve 38. The hot water from the tank 22 will ilow through the conductor 3 1 and through the branch and lift the valve 39 and pass into the' adjacent header, when the valve 37 is closed. 11" the valve 37 is opened, the boiler pressure will close the ci'ral: valve hot water will be discharged through the branch for such purpos s as may be desired, as for has water radiators or tor bathroom or purposes.

The boiler 1 it-ofl valve 4:1. inn the valve 4&1 vsane may be sup lied the pipe 4&0 for y desired purpose.

When the tu cs 13 heated by the gaseous products oi combustion from t e burner i l or the furnace 15, the flow of water through the tubes 13will be tothe let't viewed in Fig. 1, so that water in the will pass through the tubes l3 to the left header and thence'through the pipe 12, which is at the left, into the boiler 1, the water returning from the boiler'into the right header through the right pipe 12. The boiler may be replenished with hot water from the tank 22 by means oi the overflow condu" tor 84 and branch 36, by open ing the valve 2% and closing the valve 37, as already described.

Steam forming in the boiler 1 will enter the dome 2 and will pass therefrom, when the valve 25 is opened, through the con ductor 20 and downwardly through the condensing coil 21, in which the steam will be condensed to term distilled water, which will pass by the conductor 20 and the branch 26 into the distilled water container 27, until the float valve 30 is lifted and closes the vent pipe 29, at which time the check valve 33 will open, thus permitting distilled water to automatically discharged into the left header, as viewed in Fig. 1, when water is not passing through the branch 26 into the container 2. to replace distilled water drawn from the container 27 through the draw-0d cook 28. l i hen the latter is opened, distilled water is discharged therethrough, upon which the Heat valve 30 lowers anddistilled ".vater passes into the container 27 through the branch 26, the check valve 33 at such time being closed by boiler pressure.

By having the gaseous products of cornbustion pass between the tubes 13 and a boiler, a conductor connected its ends respectively with the boller above and be low the water line thereof and having a valved outlet, check valve in the conductor, opening toward the boiler, intermediate 01: the outlet ant the 'liainge end of the conductor, and means i. condensing steam in sa'd conductor intermediate of the intake end thereor and said outlet.
